MIT has recently published the paper "Up in Smoke" by Rema Hanna, Ester Duflo and Michael Greenston which studies the a randomized installation of the Chullah in India. The study participants received skilled help in installing the Chullah stove and minimal help in maintaining them.

From GEO BIOCHAR STOVE
From GEO BIOCHAR STOVE

* About 30% biochar production
* 3 to 4 days for a batch of charcoal production
* Continuous hot water access (pot 1)
* Highly suitable for institutional cooking and as well making biochar
* Additional heat generated by flaring the pyrolysis gases, used for cooking
* Mitigation of the emissions during the pyrolysis by flaring
* Costs about Rs. 3000 for a 2’ width x 5’ depth x 6’ hight (in feet) “GEO Biochar pit stove”. (cost including, tin sheet for cover, digging the pit, three pot stove and chimney.)

*_"GEO BIOCHAR STOVE" is designed by Dr. N. Sai Bhaskar Reddy, CEO, GEO. Demonstrated to farmers under the project Good Stoves and Biochar Communities Project, being supported by GoodPlanet.org, France

Fuel, Stoves and Water for Haiti
January 27, 2009

There are several projects to supply fuel, stoves and potable water to Haiti. Some have been been ongoing since before the quake and some. The organizations we know of are:

CHF International, Helps (Water Purifier)
To donate a $35 water purifying system, go to https://secure.helpsintl.org/store/haiti.php

Legacy Foundation (Fuel Briquettes)

Miombo, Project Haiti www.prohaiti.org
Peko Pe TLUD pellet fueled stoves to be distributed by Project Haiti. Pellets from Georgia.

Trees, Water, People TWP
Ananda Marga Universal Relief Team AMURT http://www.amurthaiti.org/ and
Recho Rocket stove made from mud formed in a bucket, the Haiti Rocket Stove
Stovetec Rocket Stoves in a metal bucket.

World Stove, International Lifeline Fund
Biucci, Everything Nice TLUD stoves fabricated in Haiti. Pellet fuel from Florida (Green Circle). Grass pellets to be made in Haiti.

Dear Tom,

we had developed, during the 1990s, a series of mud stoves, which not only possessed a higher fuel use efficiency but which also reduced the harmful emissions when compared with the emissions from traditional stoves used by the local people. They are made and sold even today by rural artisans trained by us. The cost is in the range of US$2 to 5. In 2003, the Shell Foundation came forward to support our stoves programme, but we had to stop promoting our own mud stoves, and we were allowed to propagate only models approved by Shell Foundation. The approved models had much lower emissions but they carried a price tag in the range of US$15 to 25.

One of the conditions laid down in this project was that the stoves must be propagated through commercial channels, without subsidy of any kind. We failed to achieve the targets set under the project, and because of this reason, Shell Foundation withdrew their support. We still sell the stoves approved by Shell Foundation but our clients are not the rural poor.

We have not given up our efforts to improve the performance of the simple mud stoves. The latest attempt is a model in which the body of the stove is made of a porous material, which has a high insulative capacity. The emissions are much nearer to internationally accepted standards. This stove costs about US$10, and if mass produced, it can be supplied at a price of about US$6 to 7

Fuel Briquette Burning at Stoves Camp 2008

This prototype was to check the hole of the briquette and how gasification can do a nice job. As said, starting the fire with few small sticks and then after preheating the chamber, briquettes ignite by themselves and burn throughly. You can help flames with having a stick in the hole while burning. I really liked how the briquette retained its shape after it burned out, so you could still push the next one it without preventing the draft..

But the briquette burned with the surface lit from the combustion chamber, as Larry predicted. You could literally walk away of the stove with the consistent flame going on all the time (I guess the briquettes were good quality :) The air inflow was only through the hole of the briquette.

Funny was, that even when one briquette burned out, the next one ignited and the airflow continued through the hole of the first briquette.

Mdula: A DIY Mud Cooking Stove
Rok Oblak, August 2008

MdulaMdula

Mdula or Modular Mbaula (stove) is a design project aiming to simplify the construction of an efficient household mud cooking stove for extreme rural areas. It is based on a Do-It-Yourself (DIY) construction techique using a simple wooden mold.

Rok Oblak has started a blog on the development of the Mdula at:

Fuel Efficient Stove Programs in IDP Settings - Summary Evaluation Report, Darfur
Academy for Educational Development for USAID, December 2008

1. INTRODUCTION: EVALUATION OBJECTIVES
Around the world, conflict and natural disasters have displaced millions of people. Displaced populations fleeing to settlement camps and seeking safety in host villages often put great stress on natural resources, leading to environmental degradation and conflict with local populations. One of the greatest needs of people affected by crisis, be they displaced, settled, or on the move, is firewood or some other type of fuel to cook their food, heat their homes, and treat water for drinking and food preparation. The risks endured (especially by women and children) collecting scarce wood resources constitute some of the most challenging and serious protection concerns both in IDP camps and in villages where conflict over resources is high.

Fuel Efficient Stove Programs in IDP Settings - Summary Evaluation Report, Uganda
Academy for Educational Development for USAID, September 2007

Introduction: Evaluation Objectives

Around the world, conflict and natural disasters have displaced millions of people. Displaced populations fleeing to settlement camps and seeking safety in host villages often put great stress on natural resources, leading to environmental degradation and conflict with local populations. One of the greatest needs of all people affected by crisis, be they displaced, settled or on the move, is firewood or other types of fuel to heat their homes, cook their food, and treat water for drinking and food preparation. The risks endured (especially by women and children) collecting sometimes scarce wood resources constitute some of the most challenging and serious protection concerns both in IDP camps and in villages where the conflict over resources is high.

USAID’s Office of Foreign Disaster Assistance (OFDA) has been one of the key US Government funders of humanitarian agencies implementing fuel-efficient stove (FES) programs in IDP settings. The FES programs are intended to help the agencies accomplish various goals, such as improve food security or decrease deforestation, by reducing fuel consumption. However, the large number of implementers, their varying motives and degrees of expertise, and differing conditions within and among IDP communities have made it difficult for OFDA to determine the relative efficacy of the FES interventions and provide guidelines for USAID-funded entities working in IDP settings.

Therefore, OFDA enlisted the assistance of the USAID Energy Team to undertake a multi-phase evaluation in order to derive “best practices” for future FES interventions. While the primary purpose of this evaluation is to provide guidance to USAID-funded organizations, USAID hopes to inform the broader humanitarian community by sharing the results of the evaluation with them as well. Eventually, the best practices will be developed into a series of recommendations and toolkits for use by NGOs, donors, and other groups operating FES programs in IDP settings.
